Bind a simple integer array to a DropDownList in MVC3

Question

My ViewModel is as follows:

public class ClassificationCalculatorIndexViewModel
{
    public bool PlacementYear { get; set; }
    public int[] Credit { get; set; } // List of Integers
    public int selectedCredit { get; set; } // Somewhere to store selected integer
    public List<YearOfStudy> StudyYear { get; set; }
}

I am struggling to bind the Integer array to a DropDownList helper object in my Razor view, I am doing the following:

@Html.DropDownListFor(Model.selectedCredit, Model.Credit)

But getting errors, I tried Googling, but found nothing of the same nature :(

The type arguments for method DropDownListFor<> cannot be inferred from the usage, try specifying the type arguments explicitly — J86

I think you need drop down for selectedCredit filled with items from Credit property:

@Html.DropDownListFor(m => m.selectedCredit, new SelectList(Model.Credit))

You need to create a SelectList object with the content of your int[].
